Darwin alderman Gary Haslett says a commemoration of World War II would be a better choice for a public art sculpture at East Point than a planned sculpture of a box jellyfish.

Mr Haslett today told ABC Local Radio in Darwin that a community public art committee had chosen a $150,000 "jellyfish on a stick" to be situated at the entrance to East Point, a reserve less than 10kms from the city centre.

"I have seen both and I really like the Bombing of Darwin idea for the entry statement," Mr Haslett said.

"The box jellyfish has been passed, so it is happening," he said.

Mr Haslett voted against building the jellyfish but said public art is subjective and it was unlikely everyone would ever agree on a proposal.

Darwin Military Museum director Tom Lewis said the public art should instead commemorate the Bombing of Darwin.

The museum is located at East Point and in World War II the area was occupied by the defence forces.

Mr Lewis said a proposal from the museum would probably also cost $150,000 and would be four metres long and made of concrete and steel.

The museum's proposal was abstract but would include four scenes from World War II, he said.
